关于油气开发地震学的思考

On hydrocarbon development seismology

应用地震学从油气勘探领域向开发领域推进过程中遇到的问题是多方面的。本文根据作者多年来对地震资料内涵的探索和对当前地震方法与技术中存在问题的理性分析,指出开发地震学不能简单地套用勘探地震学现有的理论、方法和技术,而应当从概念上和基础资料上有新的突破。否则,地震探测方法在油气开发过程中将被边缘化。开发地震学需要以高信噪比、高分辨率、高保真度为基础。地震资料处理、解释和研究一体化是开发地震学发展的重要方向。当前国际石油工业发展的现实也证明,开发地震学还没有深入到油气开发过程中去。

The applied seismology has encountered many problems when it extends from oil and gas exploration field into oil and gas development field.The petroleum development seismology, initiated in 1970s,has not yet applied in oil and gas production processes on a large scale basis. In this paper, problems existed in the seismic methodology and technology are analyzed theoretically based on the author's research on seismic data processing and interpretation of many years.It is pointed that development seismology can not just simply use the existing theory, techniques and methods in the exploration seismology and a new breakthrough is required in concepts and raw data. Otherwise, seismic methods will be in danger of being marginalized in the hydrocarbon exploration processes. The seismic data with high signal-to-noise ratio, high resolution and high fidelity are needed to fulfil the research on development seismology. Integration of seismic processing, interpretation and research is one of the important directions of development seismology in the future.
